Polyferrocenylsilane block copolymers also phase separate in solid state to generate periodic, nanoscopic iron-rich domains that can be observed by TEM without resorting to staining techniques.24 This bulk self-assembly behavior has been studied with various block copolymers, such as PS-fe-PFS,24,52 PI-h-PFS,49 and PFS-b-PMMA.22 Additional self-assembly complications...

As shown in Fig. 8.9A, a full-color photonic crystal device was designed and fabricated in a form of electrochemical cell (Arsenault et al., 2007). The device was based on a two-component composite, that is, silica microspheres and polyferrocenylsilane (PFS). The silica microspheres with an ordered self-assembly array were deposited on ITO glass substrate and served as the inactive structural scaffold. PFS with pendant unsaturated C=C bonds were incorporated into the lattice spacing of silica microspheres and polymerized...

Based on the studies of organic block copolymers (see Chapter 1, Section 1.2.5), polyferrocenylsilane block copolymers can be expected to self-assemble in solvents which are selective for one of the blocks. In the case of organic block copolymers, most studies have led to the identification of spherical structures, where the less... 

Polyferrocenylsilane block copolymers in which the blocks are immiscible (which is generally the case) would be expected to self-assemble to form phase-separated organometallic domains in the solid state. Based on the classical behavior of organic block copolymers, thin films of polyferrocene diblock copolymers would be expected to form domains such as spheres, cylinders, double diamonds (or gyro-ids) (or their antistructures), or lamellae (Chapter 1, Section 1.2.5). The preferred domain structure would be expected to be controlled by the ratio of the blocks, their degree of immiscibility (as defined by the Flory-Hu ins interaction parameter x), and the overall molecular weight of the block copolymer [159]. 

Water-soluble polyferrocenylsilane polycations, belonging to the rare class of main chain organometallic polyelectrolytes, have been reported by us and others. "" These compounds are of interest because they combine the unusual properties of polyferrocenylsilanes with the processability of polyelectrolyte solutions, for example, enabling one to make use of ionic interactions to deposit these polymers onto substrates. Polyelectrolytes can be employed in layer-by-layer (LbL) self-assembly processes to form ultrathin multilayer films with controlled thickness and composition. ...
